3D optical tomography in the presence of void regions

Abstract

We present an investigation of the effect of a 3D nonscattering gap region on image reconstruction in diffuse optical tomography. The void gap is modelled by the Radiosity-Diffusion method and the inverse problem is solved using the adjoint field method. The case of a sphere with concentric spherical gap is used as an example.
